Abstract: The effects of heat treatment process on antibacterial property,corrosion resistance and hardness of 1Cr13 martensite stainless steel containing Cu and Mo were studied.Heat treatment process was designed by uniformity design and the results were analyzed by regression equations.The results show that antibacterial rate and hardness have maximum values after solution at 1 200 ℃×15 min and aging at 550 ℃×1 h and hardness is 40.6 HRC,antibacterial is 100%.The corrosion rate of 1Cr13Cu3Mo decrease with time to zero.
